The ID field was specifed as primary and self incrementing by 1 and the table has one username and password (being Id: 1, Username: peter, Password: admin). The Login form works, it checks to see if the user exists, if they do, they gain access, if not a message box is displayed. The Registration form however does not and I have no idea why, its probably something simple but yeah, hence the reason Im here! When I register I can add a user fine, and it wont allow me to add the same user, but when I look at the table, it is not updated :S and I have no idea why!! Even after registering the user closing the application and starting again, say I registered the following:
Username: Fred
Password: 123
Then I login with these credentials, it works. When I close the program and reopen the program, it still works and will not allow me to register a new user being Fred, 123. However after 3 or 4 minutes when I try again, the user no longer exisits and I can re-register with set credentials? The code is shown below (1st the login form that works, second the registration that doesnt).
Public Class Login
Private Sub btnOK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnOK.Click
Dim connection As New SqlClient.SqlConnection("Data Source=.SQLEXPRESS;AttachDbFilename=|DataDirectory|Users.mdf;Integrated Security=True;User Instance=True")
I'm looking to release an application for free with (unubtrusive) ad support, and the option to upgrade to a registered version to remove the ads. Basically we want to give the product away for free, but need some income to support costs.
What would be the best way to achieve that? I essentially just want the user to be able to type in a serial number, which is sent to a server, checked and presumably moved to a list of used serials, and then the product is activated and the ads removed.
Vb.net 2008 I create registration user name and password project with Login form using My.Setting.My question when I wrote the username and password in TextBoxes . I want when checked CheckBox to save UserName and PassWord to Login again automatically.
i'm trying to link the program i'm designing so that it creates an entry and can refer to the record for the numerous pieces of information that was saved to it. I'm not sure what method would be the best to achieve this but I'm a bit short on time to have this done as it is a school major work and this is one of the final steps but me and my partner are stuck and the teacher refuses to help, probabaly because he doesn't know.
In the register I need to allow the user to input a Username, Password, First & Last Name, Email, Address and a Phone Number On the login it will only require a Username and a Password.
I'm really sorry I have not given any personal coding etc. but we simply don't know where to start.
I'm writing an asp.net page with a simple registration form that connects to my access database and inserts the values in the table. So I have my database, my registration page, everything looks fine in my code, but there's a syntax error I can't seem to figure out. When I go on my webpage and click submit, it says : Syntax error in INSERT INTO instruction.
Recently working in vb 2010 express. I'm using service-based database which is based on SQL Server. This database will be deployed at the server. Is it possible that multiple vb.net programs, which are installed in remote computers or client computers in the same network, connect to this database simultaneously? Does the service-based database support multiple connections?
This might seem obvious but I was doing some research and I was wondering if a service application start an executable. I know an .exe cannot start without some sort of logon but I was wondering if it was possible to work around this by having my service call it.
I would like to know if it's possible to stop | start | restart service as a User with a vb program?
The reason is that for some reason, I have to restart some service for a special application on certain station but the people who use them are log on as Admin and I can't go there each time or use vnc.
Is there for my .Net application to detect if a user has logged on? It is a Windows Service, so it will be running before logon.What I want to do is display a "popup" when a user logs on to tell them the status of the application
My application needs to be a service (it needs run regardless of whether a user is logged on), but I also need some sort of client control/oversight over what it is doing. What is the optimal way to do this?Write a separate application to communicate with the service application - I see that as best solution in terms of stability, since the applications will be decoupled somewhat Use callbacks on system events in the service application to load UI forms directly from the service application - I see this as being easier to deploy.
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a generic class and is not marked as [ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be exposed for such types. Consider marking the type with [ClassInterface(ClassInterfaceType.None)] and exposing an explicit interface as the default interface to COM using the ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
I currently have a windows service that is packaged up as an msi installer. However, during the installation i need the user to input their required filepath (to string) location. The filepath variable currently resides in my component class called MyNewService that is inherited from System.ServiceProcess.ServiceBase.
Is there anyway i can allow the user to define the filepath variable during installation?
In Windows Vista/7/2008/2008R2, is it at all possible to launch a process in a user's session from a service? Specifically, the local session would be most useful.Everything I've been reading seems to say this isn't possible, but I figured I'd ask here before giving up completely.My service signs on as Local System.
This is the function that I use in web service for getting current windows user.
<WebMethod()> _ Function User() As String Dim p() As String = Split(My.User.Name, "")
[code]....
When I run service on localhost it realy return current windows user name!The problem is when i run service from remote PC, in that case I got nothing from this function. What is problem with this service, and how I can get name of Windows user?
I have created a windows service that has the Account set to user. Which means that when I install the service I need to pass a user name and password. Is there a way to set these maybe in the ProjectInstaller class maybe in the BeforeInstall event? if so HOW?
My app (which runs ok as a standard user) requires updates to be installed, but I don't want to have to input the administrator username/password each time nor do I want to increase user privileges to administrator.
I have a windows service which handles the downloading of updates etc (running as Local System) but the start command needs to come from the main app (running as a standard user). This is not permitted and I get Access Denied.
I understand why this is happening but is there an alternative way to achieve this? I want to handle program updates as the standard user without using ClickOnce or installing to a non Program Files folder.
I created a function that allows me to login to my web service. I created a session here and added some values I retrieved from a stored procedure.[code].....
My question is: I have a default.aspx and a master page, how can I redirect the user when their session is active? For example, the default page tells users that access is forbidden untill the login/register.Do I have to use the form load handler for default.aspx or the masterpages' load handler? How do I check weither the usersession is active?
I am jsut adding bits on to a Windows Service we are making here at our company, its an Asset Management tools with a few built in extras. It runs as a service on everyones machines but we can also do things like request a reboot etc through it.At the moment when We send a Reboot/shutdown etc command to it the Service on the machines calls 'C:WindowsSystem32Shutdown.exe' with the appropiate switches. This displays the windows shutdown warning to the users but nothing they can do about it.
What I was wondering if I create a seperate exe (or even better built into the service but I am not sure if this is possible) instead of the Service Calling 'shutdown.exe' it calls this form up to the user which states that we have requested a reboot etc but there is a 'Cancel' option. The Cancel can just end the form/program and nothing more, if the timeout that we specify is reached then that form/program then calls shutdown exe for an instant shutdown.
I know that the Service runs in a different user Space and we have no telling of who is logged on to that machine so I will need a way to just launch the form to any logged on users. Doesn't matter to much if there is no one logged onto the machine but if it does display this form while noone is logged on that is not a big deal.
I've been developing in .NET (VB, C++, C#) for a number of years, but I am finally creating my first service application (in VB). I need to read/write to a file contained within a user's documents. As a service is not associated with a particular user, would a service have access to a user's documents? ...regardless if that user is signed on or not?
Recently while I was playing with VS 2008(VB), I have created an application for folder sync purpose... which is working fine. Then, I have created a windows service that does the same thing and it is also working fine(from application perspective). But, I have been trying to add some additional functionality to that new service. It keeps on running as long as System is ON.
But I would like to change the functionality to... as soon as user logs off Service should STOP, and should START when user logs into that PC. I tried to find some useful info online(related to my task) and all I could come up with was to add OnSessionChange(...) method to the service. But for some reason it is not working out for me(when I've logged off or other system events such as 'system lock').
I need to get the user input for where they want the files that will be produced by my windows service to be stored.
I was thinking that i could do this by reading in the user's input to a variable in the on start event of my service? this variable is then later used in my xml writer.
I have developed a windows services that Log On As "Local System" account with Statup Type "Automatic". I understand that windows services starts before user logins. But I want my service to start when ever user logs in.
If I create a scheduled task for my vb.net program, and run it under another user, and it runs when logged off, as long as the user has full rights, will the winforms application be able to call web services over the web?
I developed a windows service project using vb.net and windows service is installed with logon account as admin's user name and password. Target of windows service is to read the pst file path location from windows registry for currently logged user by accessing the following registry key
The problem is , windows service can able to read the admin pst file path location if admin is logged in windows. When other user logged in windows, service is not able to read currently logged user's pst file path location from registry because of windows service is configured with admin user name and password. so it always reads admin's pst file location.
I'm writing a windows service in VB.Net and set the service process installer's "Account" property set to "User". So when I tried to install the utility using INSTALLUTIL.EXE it is prompting to enter the user id and password. So I wanted to suppress this "Set Service Logon" so added below code to ProjectInstaller.vb and I was able to do what ever I want: [code]
I need to return an error message to the client, if they have entered invalid data when calling my web service. So if my code is: [code]Is there a way to display a more user friendly error message (such as a message box or just the words "Invalid Order ID")?
I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.
Service running under system account (in this example a simple console application)
Code:Imports ClassLibrary1Module Serv Sub Main() Dim SDSIPC As Semaphore = CType(Activator.GetObject (GetType(ClientFromServer), "ipc://Client/SreeniRemoteObj"), Semaphore) SDSIPC.DoSomething()
